Latent print examination

Latent print examination involves analyzing invisible or barely visible fingerprints left on surfaces after contact. Experts, called fingerprint analysts, use specialized tools and techniques—like dusting powders or alternate light sources—to make these prints visible. They compare the unique patterns and ridge details of these prints to known prints in databases to identify individuals or confirm if a print matches a suspect. This process is a vital part of forensic investigations, helping link a person to a crime scene or exclude others, ultimately providing valuable evidence in criminal cases.
